Combining like terms in the given expression makes it simplify to ...
(2x -18x) +(14y) +(9 -10) = -16x +14y -1
We are to compare this expression with the offered expressions to see if they simplify to the same thing. We'll examine those left-to-right starting with the top row:
- 2x -18x +14y -19 = -16x +14y -19 . . . not the same
- -2xy -1 . . . not the same
- 16x +14y -1 . . . not the same
- 9 -16x +14y -10 = -16x +14y -1 . . . equivalent
- -16x +14y -1 . . . equivalent and simplified
- 2x -18x +14y -1 = -16x +14y -1 . . . equivalent
Answer:
An exponential function with a growth factor of 1/2 would have 1.5^x as part of it.
The exponential growth function is as follows.
r is the rate of growth (0.50)
Answer:
44,280
Step-by-step explanation:
I might know. I multiplied the 1st and got 307.5.
then multiplied the 2d. I got 144
multiplied 307.5x144 and I got 44,280
if the number of boys is x ,then the number of girls is x+7,so 2x+7=35,we can know x=9,so the number of boys is 9,and girls are 16
